3. Writing Skills That Actually Work

A skill is a written procedure the AI follows when it's relevant to your task — how to structure a report, qualify a lead, or review code. Instead of repeating the same instructions every time you chat, you write them once as a skill and the AI applies them automatically. But here's the catch: vague skills like "be professional" do absolutely nothing. The AI needs operational, step-by-step guidance to change its output. That's why how you write a skill matters as much as whether you create one at all. A well-written skill has three ingredients:

1. One job per skill — don't bundle multiple procedures together. A skill called "Handle everything about clients" is too broad to be useful.
2. A name that states when to use it — the AI uses the name to decide relevance. "Qualify an inbound sales lead" beats "Sales stuff."
3. Numbered operational steps — write it like a checklist for a competent colleague. Each step should be an action, not a wish.
4. A stated expected output — tell the AI what the finished result looks like (e.g., "End with a one-paragraph recommendation").

Skills that follow these rules change results. Skills that don't are invisible.

Let's see the difference between a weak skill and a strong one.

Weak skill: Name: "Email help" Steps: "Write good emails."

This gives the AI nothing to act on. It's the equivalent of telling a colleague "just do it well."

Strong skill: Name: "Draft a client follow-up email after a discovery call" Steps:

1. Open with a thank-you referencing one specific topic discussed.
2. Summarize the three key needs the client mentioned.
3. Propose a next step with two date/time options.
4. Keep the tone warm but concise — under 150 words. Expected output: A ready-to-send email the user only needs to personalize with names and dates.

Notice the strong version has one job, action verbs, and a clear expected output. Write every skill like a checklist for a competent colleague — precise and action-oriented.

Once your skill is written, it needs to be active to work. Only active skills are offered to the AI in ChatPro and OUPI Studio. You can deactivate a skill to bench it without deleting it — handy for seasonal procedures or drafts you're still refining.

For your most critical procedures, use pinning. A pinned skill stays prioritized when the AI assembles its context, so it's always considered first. Reserve pinning for the procedures that should apply to virtually every task you do.

If you edit a skill, active conversations will pick up the new version on their next use — so you can iterate and improve without starting over.
